Durations with time components before T are parsed successfully

[Matti Niemenmaa]

If you forget to put a T before time components in a duration, they are parsed successfully but the time components are ignored:

>>> aniso8601.parse_duration('P1S')
datetime.timedelta(0)

>>> aniso8601.parse_duration('P1D1S')
datetime.timedelta(1)

>>> aniso8601.parse_duration('P1H1M')
datetime.timedelta(30)

I would expect exceptions to be raised instead.

This is with aniso8601 1.1.0.

[Brandon Nielsen]

Fixed in 1.2.0.
